According to Erichsen, CBT uses techniques such as bedtime restriction for two weeks in order to improve sleeping habits, which means going to bed later than normal and restricting time there to five or six hours.

Another technique is called stimulus control, meaning you only use your bed for sleeping, not eating or watching television.

If all else fails, Erichsen says cranial electrode stimulation is an option that will deliver serotonin to your brain painlessly through electricity.
